I did that from your original post #3 and again, it removes the notice entirely and is nowhere to be seen on the entire forum. It removes it from the main forum page as well, which is where I'd like it to show up. This has the same effect as if I had unchecked "notice is active" from the control panel, just like setting the Controller and Action is as you suggested as an alternative.
I really appreciate the effort. I think we'll have to find another way to do it. Maybe a css template change or something of the kind. It's mind boggling that something which appears so simple, just doesn't work.
